House Extension Drawings in Borough |

Borough sits inside Southwark, so every application here is determined by Southwark Council against the Southwark Local Plan.

What is house extension drawings in Borough?

House Extension Drawings in Borough are survey-based Borough drawings for a rear, side or wrap-around extension in SE1. Southwark Council is the authority for every SE1 address, they fix the Borough depth against permitted-development limits, answer the 45-degree amenity test Southwark Council applies, and locate the party wall on the georgian and victorian terraces, and the Southwark Local Plan sets the policy test.

Do I need house extension drawings in Borough?

An Article 4 Direction applies across Southwark, so check it before assuming Borough permitted development survives. You cannot design for Borough without accounting for the fact that it is Georgian and Victorian terraces, market quarter. Southwark has 43 conservation areas, and Borough is the one that most often covers Borough stock. We plot the Borough site against the designation before quoting.

That mapping of Article 4 directions across Borough happens before design, which is what keeps the Southwark Council route predictable. Rear wall, floor levels and the Borough Market roofline are the three Borough constraints. The borough policy layer over every SE1 address is set out on Southwark planning. The Borough survey then carries into architectural drawings in Borough if the project runs on to construction.

Borough programme

How long does Southwark Council take to decide?

Most Borough delay happens before the clock starts: London Borough of Southwark takes one to two weeks to validate, and an incomplete pack goes to the back of the queue. The Borough job starts with a laser survey, not a sketch.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

An officer report on the SE1 case is written after the consultation closes. Every Borough submission leaves here as a PDF set at the scales Southwark Council requires.

Objections on a Borough case usually come from the immediate neighbours, not the wider SE1 area. The Borough survey records every opening, level change and structural wall.

Party wall procedure runs alongside the Borough application, not after it. Once consent is granted, planning permission follows for the SE1 property.

Surveying in SE1

What Borough's housing stock means for your plans

Borough is characterised by georgian and victorian terraces, warehouse conversions, concentrated across SE1 in the Bermondsey / Borough / Waterloo area. Borough rewards a survey-first approach: the georgian and victorian terraces rarely matches its own original drawings. Locally that resolves to this: georgian rear elevations here are usually the listed or locally listed face of the building, so a glazed link and a lightweight rear addition tend to fare better than a full-width box. That is the Borough constraint Southwark Council will look for. Because the Borough streetscape near Borough Market is consistent, departures in ridge height read immediately in an officer report.

Southwark sets no special basement rule, so a Borough lower-ground scheme stands or falls on the engineering and the neighbours. If a Borough project extends into building regulations drawings for SE1 properties or loft conversion drawings, the survey is already done.

What the Borough drawing pack contains

Everything a Borough submission needs is in the list below.

  • existing and proposed ground-floor plans for the Borough property
  • proposed rear elevation
  • long section through the extension
  • site and block plans
  • party wall position drawing

What housing stock do you handle in Borough?

We draw houses, flats and conversions across SE1; the georgian and victorian terraces dominates.

Where else in Southwark do you work?
